Hello You!

This is an R Markdown Notebook. When you execute code within the notebook, the results appear beneath the code.

When you save the notebook, an HTML file containing the code and output will be saved alongside it (click the Preview button or press Cmd+Shift+K to preview the HTML file).

The preview shows you a rendered HTML copy of the contents of the editor. Consequently, unlike Knit, Preview does not run any R code chunks. Instead, the output of the chunk when it was last run in the editor is displayed.

You can write HTML and embed a Google Form

Count languages

languages <- as.character(rawDF$languages) %>% corpus
summary(languages)

Corpus consisting of 2 documents, showing 2 documents:

  Text Types Tokens Sentences
 text1     6      9         1
 text2     3      3         1

dfm <- tokens(languages) %>%
  dfm  %>% convert(to="data.frame") %>%
  select(!contains(",")) %>%
  summarise(across(where(is.numeric), ~ sum(.x, na.rm = TRUE))) %>%
  pivot_longer(everything(), names_to = "language", values_to = "count") 
dfm

Create plots

Simple

proficiency <- table(rawDF$proficiency)
barplot(proficiency,
   xlab="Proficiency Score", ylab="Score Count")

Styled

p1 <- ggplot(dfm) +
  aes(x=language, y=count, fill=language) +
  geom_col()
p1

Interactive
